Definitions
- optical holders mounted conventionally must hold lenses having different diameters at a preselected height and at the same time allow lenses to be quickly interchanged.
- optical holders for lenses or similar optical devices, and particularly holders in which lenses were interchangeable were expensive. Furthermore the process for changing the lenses was time consuming.
- lens holders presently available are capable of holding lenses having a relatively small range of diameters.
- several separate holders of various sizes must be acquired.
- Melles Griot Optics Guide 4 published in 1988 by Melles Griot 1770 Kettering Street, Irvine, Calif. 92714 , page 21-19, two lens holder models are shown: one for lenses having diameters of 5 mm to 25 mm, and a second for lenses in the range of 25 mm to 80 mm diameter.
- Another objective is to provide a lens holder which can hold lenses having a relatively large range of diameters.
- Yet a further objective of the invention is to provide a lens holder which maintains its accuracy despite extensive usage.
- a holder constructed in accordance with this invention comprises a frame, a plurality of arms pivotably secured to the frame, and linking means connected to the arms for moving the arms simultaneously by the same angle.
- the arms have arm ends which in one position are disposed adjacent to a common point within the frame.
- the arms may be separated to accept a lens or other similar optical device, and hold the lens with its center coincident with the common point which is preferably disposed at the center of the lens holder.
- a lens holder constructed in accordance with this invention has fewer parts and is simpler to manufacture then the devices described above.
- FIG. 1 shows a plan view of a lens holder constructed in accordance with this invention in a closed position
- FIG. 2 shows the holder of FIG. 1 engaging lens
- FIG. 3 shows a sectional view of the arms holding a lens, taken along line 2--2, in FIG. 2
- a plurality of arms 18, 20, 22 are pivotably mounted on the frame 16 by corresponding pins 24, 26, 28.
- the arms could be pivotably mounted on frame 16 by screws threaded into corresponding holes within the frame.
- the longitudinal axis of the pins defines a pivoting axis or fulcrum for the arms 18, 20, 22.
- the pins 24, 26, 28 are equidistant from each other having an angle of 120 degrees between their axes to insure that the lens is automatically centered independently of its diameter.
- the arms have inner ends 30, 32, 34 which in FIG. 1 are shown disposed adjacent to each other and to center 36 of the frame 16.
- each arm extending from the corresponding inner end to the pin is approximately L-shaped with the shorter leg of the L being disposed closer to the common center 36 then the longer leg.
- the inner ends 30, 32, 34 are generally rounded and are provided with a shoulder 37 for engaging and providing a back support for a lens 72.
- Arm 18 has one extension 38 terminating in a coupling pin 40, and a second extension 42 terminating in a pin 44. The two extensions are disposed at an angle of 60 degrees.
- Arm 20 has a single extension 46 terminating in a coupling pin 48. There is an angle of 60 degrees between arm 20 and extension 46.
- arm 22 has an extension 50 terminating in coupling pin 52. Between pin 40 and 52 there is a linking bar 54, and between pins 44 and 48 there is another linking bar 56.
- Linking bar 56 has a downwardly extending trigger 58 at one end, and a downward extension 60 at the other end terminating in a hole 62.
- frame 12 Adjacent to trigger 58, frame 12 has an extension 64 terminating in a hole 66.
- a resilient means such as a coil spring 68 which is pre-strained during assembly, and which urges the arms in the clockwise direction toward a closed position shown in FIG. 1.
- the protective sleeve 70 may be slidably mounted on the spring 68.
- the operation of the lens holder shall now be described for the configuration of FIGS. 1 and 2.
- the inner ends of the arms are held in the closed position shown in FIG. 1 by spring 68.
- the arms are opened by pulling the trigger 58 to the right.
- the arms and the linking bars are arranged and dimensioned so that as the trigger is pulled to the right, the arms are pivoted counterclockwise simultaneously by the same angle around their fulcrums, so that the arm ends 30, 32, 34 are always at the same distance from each other and from the common center 36.
- a lens or other optical device may be placed between the arm ends.
- the arm ends engage the perimeter of the lens and hold it securely. After the trigger is released, the lens remains secured to the holder by the force of spring 68.
- the L-shaped arms are arranged and constructed so that they substantially do not extend into the inner region of the frame 16. This feature of the invention permits the holder to accommodate lenses having an external diameter only slightly smaller than the inner diameter of frame 16. Importantly, the structure and orientation of the arms assures that the center of the lens being positioned automatically coincides with the common center 36, as shown for lens 72 in FIG. 2.
- the arms of lens holder of FIGS. 1-3 may have for example a square cross-section of about 0.187' and the free ends may be terminated by a section having a reduced thickness of about 0.156" with a thickness at the shoulder of about 0.031".
- a holder with these dimensions and a frame aperture of 4.00" may be used to support lenses of up to 0.5" thickness, and diameters in the range of 3/32" to 4".
- the arms may be provided with rods, screws or other support means well-known in the art. If there is need to hold and center optical elements having a diameter exceeding 4.00", a holder with a larger frame aperture can be made.
- the shoulder 37 may be formed integrally with the arm or it may be secured to the arm.
- the arm itself and its inner ends can have a variety of other shapes besides the L-shape described above.
- the arm may be straight and may have a side surface arranged to engage the lens.
